IMPROVEMENT IN STEAM-TRAPS.

Specification forming part of Letters Patent No. 43,090, dated .I une14, 1864.

To all whom it may concern:

Be it known that I, CHARLES H. BROWN, a resident of Fitchburg, in thecounty of Worcester and State of Massachusetts, have invented auImproved Steam-Trap; and I do hereby declare the same to be fullydescribed in the following specification, and represented in theaccompanying drawings, of which- Figure 1 is a side elevation, Fig. 2 atop view, and Fig. 3 alongitudinal section, of it.

When steam is employed in pipes or drums for heating them for thepurpose of warming the atmosphere of a room or apartment, more or lesscondensation of the steam within the pipe or drum will taire place.

The object of my invention is to discharge from such a heating pipe orpipes or drum the water which may be so produced thereinviz., by thecondensation of the vapor or steamthe discharge of such water beingeffected without any material loss of steam.

While in operation the trap is to be so arranged with respect to andconnected .with the heating pipe, pipes, or coil, or steamdrum, as thecase may be, as to enable the condensed water thereof to How freely intothe expansiontube of the trap and out of its valve-opening.

In the drawings, A denotes a tube ot' metal provided with a tubularelbow, B, at one end and an arm, C, projecting from its opposite end.

Within the elbow B is a partition, I), which extends across the interiorof the elbow, and is provided with a valve-opening, a, in manner asrepresented in Fig. 3. The lower part of the elbow is open as shown atb.Avalve, cfis applied to the opening a, the. stem d, of the valve beingextended laterally through and out of the elbow, and being straddled bya bifurcated lever, D. Where the said lever embraces the valvestem suchlever is arranged between two shoulders, e'f, formed on the valve-stemand close to the lever. The said lever D has its fulcrum g at or nearits upper end, and supported by an arm, E, projecting from the elbow B,in manner as shown in the drawings. A rod, F, connected at one end tothe arm C, encompasses at its opposite end the lever D, or may bejointed to it just below its fulcrum. If we now suppose the tube r A tobe secured to the lower part of the steam heatingpipe, coil, or heater,as the case may be, and so that the condensed water thereof may owimmediately into the said tube A, the operation of the apparatus may bethus described: So long as there may be steam within the tube A, suchtube will be expanded by the heat of such steam and by means of the armE will so force the lever D' against the rod F as to cause the saidlever to be moved in a manner to press the valve c t'oward its seat s,and close the opening a, such seat at the same time being by theexpansion ot' the tube moved toward the valve; but when there may be acondensation of steam within the tube A to such an extent as to causethe tube to be contracted lengthwise, the valveseat and the valve willbe moved simultaneously away from one another so as to open the valve,in which case the water of condensation will be expelled through thevalve-opening a and discharged through the opening b.

I claim- My improved steam-trap, having' its single expansion-tube A,the valve-opening a, the valve c, the valve-lever D', the arm orfulcruin supporter E, and the lever-operating rod F, arranged andapplied together, substantially in manner and so as to operate asspecified.

CHARLES H. BROWN.
